20 because
Step-by-step explanation:
you have to add all of them then ÷ by 2
Answer:
3 hours, duh
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 17.16 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 17.16 is 100%, so we can write it down as 17.16 = 100%.
4. We know, that x is 62.4% of the output value, so we can write it down as x=62.4%
5. Now we have two simple questions:
1) 17.16 = 100%
2) x=62.4%
Where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
17.16÷x=100%÷62.4%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 62.4% of 17.16
17.16÷x=100/62.4%
(17.16÷x)×x=(100÷62.4%)×x
17.16=1.60256410256×x
(1.60256410256) to get x
17.16÷1.60256410256=x
10.70784=x
x=10.70784
Now we have:
62.4% of 17.16=10.70784
So 10.70784 is your answer
Hope this helps :)
Yes it is easy what u all have to do is to check that by which number or fraction is the equation being divided or multiplied, here in a it is multiplied by 10 so it will be 2
in b it is being divided by 100 or multiplied by 1/100 both are same so b will be 340 in first blank and in second it will be 0.034
in c it is being divided by 10 so in first blank it will be 85700 and in second it will be 857 and in third it will be 0.857
in d it is being multiplied by 10 so in first blank it will be 44400 in second it will be 444000 and in third it will be 4440000
in e it is... in the first blank it will be multiplied by 1/100 and then in second blank it will be multiplied by 100 so first blank will be 0.095 and second will be 9500000 and third blank will be 950000000
